Couldn't help but think about this:

When we talk about jigging, it is pound the bottom, maintain bottom contact or face not getting bit.

Trolling, look for fish up in the water column… the most active fish.

I get the thought behind both for sure… but there is something odd about the concepts when you compare them. Like the polar opposite reasoning applies based on what you have tied on. Too much time on my hands thinking of fishing I guess.
